在x86 架构的Cache 光谱线上,有 read 和 write 都 cache 的 Writeback 模式(简称 WB),有 read 时 cache,write hit 时同步写入 cache line 和 main memory,而 write miss 时不分配 cache line(即没有 write allocate),直接写入 memory 的 Writethrough 模式(简称 WT)。 图-1 而上图绿框的这个代表 Write...
在Multi-Processor 的環境下,CPU 必須監控其它 CPU 對系統記憶體以及 Cache 的動作,以確保所有的 CPU 狀態能夠同步。 Memory Type 根據不同的需要,CPU 可以對系統記憶體執行不同的 Cache 動作。 String Uncacheable (UC) 不能被 Cache Uncacheable(UC-) 不能被 Cache,但是可以借由 MTRR 的設定,修改為 WC (...
